A lot of people have contacted me asking whether they could port WP-Cumulus to their CMS of choice. While it’s nice of them to ask, the GPL license wouldn’t let me stop them even if I wanted to. Which I don’t. I love how this little project of mine is spreading like wildfire. I’ve hardly been able to keep up with the comments on my blog and the Cumulus-related email I get. I now know what people mean when they say the response has been overwhelming.

So to answer this question once and for all: Yes, you can. As long as your stick to the GPL license you can do anything with WP-Cumulus. If you port Cumulus to a new platform, please let me know so I can write about it in posts like this.

Here are three(!) new ports recently released by their respective authors. Thanks to Christian Philipp (TYPO3), Rob Antonishen (Serendipity) and Big Bear (Joomla) for their work.
